All ball valves shall be factory cleaned for oxygen service, individually bagged, and shall conform to NFPA 99 standards.

Each 1/2″ to 4″ valve consists of Teflon/Viton seats and adjustable stem packing gland with a Teflon stem seal.

All ball valves are rated at 400 psig, as well as full vacuum (29.9″ Hg). Valves go from full ON to full OFF by turning the vinyl-gripped valve handle 90°.

Latching handles may be ordered separately when required.
